Hello All, just picked up a reasonably sized, elderly Navaja with a lion trademark on the blade. I'm hoping that someone here who has more knowledge of these knives may be able to tell me something about the maker.

I have some pic's of the knife which I'll put up when I've reduced the image sizes.

Fernando, thank you for pointing me in the right direction, I've now done a little searching. It seems that Au Lion did have a moment of fame, they contracted to produce the first U.S. mod 1918 trench knives ( now much sought after ), there doesn't seem to be a lot of information on the maker.
